Your replies are similar in essence, so I just have to ask this: when was it stated that you need to reach a certain level to access awakening?
Considering Luffy fought awakening users as far back as Alabasta, where he surpassed Crocodile, then shouldn't he have awakened his DF there?
Heck, I doubt the Impel Down Jailer Beasts had better DF control than pre-Marineford Luffy and all five of them were awakened Zoan users (more so than the Beast Pirates), so, going by your answer, why didn't Luffy awaken back then?
Now, don't kid a kidder.
